Description

Technical Field

[0001] This invention relates to a device for receiving a pluggable module, and more particularly to a device for dissipating heat from a pluggable module inserted into a housing. Background Technology

[0002] US Patent No. US11700712B2 discloses a housing assembly for receiving electronic components. The housing assembly includes a housing, a floating heatsink (opposite to a riding heatsink), a pivot lever arm, and an actuator that can be deployed through an inserted electronic component to pivot the lever arm, thereby lowering the heatsink to contact the electronic component.

[0003] US Patent No. US10212852B1 discloses a device comprising a heat sink, a housing, and a spring. The heat sink has at least one stop pin at its rear and multiple guide pins on its sides; the housing has multiple sliding profile ramps for receiving the respective guide pins; the spring is coupled to the rear side of the housing. In use, an inserted field-pluggable electronic module pushes the stop pin of the heat sink, moving the heat sink downwards via the guide pins and ramps, so that the heat sink overcomes the spring force and presses against the electronic module. In other designs, the guide pins are not located on the heat sink, but rather on a separate spring plate coupled to and applying force to the heat sink.

[0004] The pluggable module in the previous case was prone to damage to the heat-conducting material at the bottom of the heat sink during the insertion process.

[0005] Therefore, an improved device is needed to overcome the shortcomings of the existing technology. Summary of the Invention

[0006] Compared with the prior art, the advantage of the device for receiving pluggable modules of the present invention is that the front part of the present invention is movably supported by a spring on the front part of the housing, such that when the housing is open, the bottom of the heat sink is inclined relative to the upper wall of the housing to protect the top of the heat sink.

[0033] Component Symbol Explanation Device 100 Casing 10 Radiator 20 Spring 30 Link 40 Front opening 12 Upper wall 16 Top opening 14 Frame 50 Clip 60 Front 202 Rear 204 Bottom 206 Thermal conductive material interface 208 Fin 22 First groove 24 Second groove 26 upper part 32 Lower part 34 Spring plate 36 Actuating link 42 Connecting rod 44 Front lever 46 Legs 422 Hole 162 Guide rail 424 462 rollers Pivot 464 Frame section 52 Connecting part 5 Inner wall 522 Upper wall 524 Outer wall 526 Groove 56 Hole 58 Linkage 70 Radiator 80 Frame 90 Actuating Linkage 72 Front slider 74 Hole 742 Pin 82 Inner wall 922 Outer wall 926 98 slender holes Detailed Implementation like Figure 1-7 As shown, a device 100 for receiving a pluggable module according to the present invention includes a housing 10, a heat sink 20, a spring 30, and a connecting rod 40. The housing 10 has a front opening 12 and an upper opening 14 provided on the upper wall 16 of the housing 10. The heat sink 20 is mounted on the upper wall 16 of the housing 10. The spring 30 supports the heat sink 20. The connecting rod 40 is disposed next to the heat sink 20 and coupled to the spring 30. The purpose of this arrangement is that in the open state, when the pluggable module is not yet inserted into the housing 10, the front part of the heat sink 20 is held and pushed by the spring 30, causing the heat sink 20 to tilt. In the closed state, when the pluggable module is inserted into the housing 10, acting on the connecting rod 40, the connecting rod 40 resists the action of the spring 30 to move the heat sink 20 from the tilted position to a horizontal position. At this time, the bottom of the heat sink 20 engages with the top of the inserted module to achieve heat dissipation. The position or orientation needs to be changed from tilted to horizontal, especially when thermally conductive material (TIM) is applied to the bottom surface of the heat sink 20 to improve thermal conductivity. Since the thermally conductive material is fragile, it is best to avoid direct contact between the thermally conductive material and the moving pluggable module when inserting the pluggable module into the housing 10.

[0034] The device 100 also includes a separately provided frame 50 and clamp 60. Additionally, the housing 10 may have an integral structure or feature to suitably hold the radiator 20 and / or other integral structures or features to facilitate the reception of the connecting rod 40. The respective structures of the housing 10, radiator 20, spring 30, connecting rod 40, and frame 50 and clamp 60 (if present), as well as their positions and operational relationships, will be described in detail later.

[0035] The housing 10 typically has a known structure; in this embodiment, the housing 10 is of a stacked type, having an upper port and a lower port. The upper port and the lower port are used for inserting an upper pluggable module and a lower pluggable module, respectively. The housing 10 may also be configured to have only a single port or one or more rows of ports. Corresponding socket connectors are disposed within the housing 10 for interconnection with one or more inserted pluggable modules. It is well known in the art that pluggable modules can have latching features, for example, latching slots and latching release mechanisms provided on both sides, and the housing 10 can have corresponding features provided on both sides to latch the pluggable modules into the housing 10. Furthermore, the forward stop of the housing 10 and the forward stop of the module can be designed to determine the forward insertion position of the module in the housing 10 in a well-known manner.

[0036] like Figure 15-16 As shown, the heat sink 20 includes a front portion 202, a rear portion 204, and a bottom portion 206. The front portion 202 is movably supported at the front of the housing 10 by a spring 30. The rear portion 204 is movably held at the rear of the housing 10, for example, by a clip 60. The bottom portion 206 is located near the upper opening 14 of the housing 10. The bottom portion 106 of the heat sink 20 has a thermally conductive material interface 208. The heat sink 20 includes a plurality of fins 22. A first groove 24 is formed at the front portion 202 for the spring 30 to cross over; a second groove 26 may be formed at the rear portion 204 for the clip 60 to cross over.

[0037] like Figure 13 and 14 As shown, the spring 30 includes an upper portion 32, a lower portion 34, and a spring plate 36. The spring plate 36 may be a pair of spring portions connected to both ends of the upper portion 32. The lower portion 34 may be in the form of one or more fingers connected to each of the pair of spring portions. The upper portion 32 is received in a first recess 24 of the radiator 20, and the lower portion 34 extends below the radiator 20. The upper portion 32 and the lower portion 34 are designed to clamp the radiator 20. The spring plate 36 is pressed between the connecting rod 40 and the housing 10. When the spring plate 36 is pressed downward toward the housing 10 by the connecting rod 40, the upper portion 32 and the lower portion 34 will cause the radiator 20 to move downward.

[0038] like Figure 10 and 12As shown, the connecting rod 40 can be a pair of connecting portions. The pair of connecting portions are located on two opposite sides of the radiator 20. Each connecting portion includes an actuating connecting rod 42, a connecting rod 44 pivotally connected to the actuating connecting rod 42, and a front lever 46 pivotally connected to the connecting rod 44, the front lever 46 being used to apply a downward force to the radiator 20. The actuating connecting rod 42 includes a leg 422, the leg 422 passing through a hole 162 (… Figure 2 The actuation link 42 extends into the housing 10 to operate during the insertion of the pluggable module. The actuation link 42 also includes a pair of guide rails 424 mounted to the frame 50. The front lever 46 includes a roller 462. The roller 462 is used for smooth movement on the spring plate 36 of the spring 30. The front lever 46 has a pivot 464, for example, a pair of pivot portions located on opposite sides of the front lever 46. The pivot 464 is also mounted to the frame 50. Therefore, the link 40 can be deployed by a module inserted into the housing 10 through the front opening 12, and when deployed, the actuation link 42 moves the connecting link 44, which in turn moves the front lever 46 to achieve pivoting movement about the pivot 464. The pivoting movement of the front lever 46 causes the roller 462 to roll downwards and backwards, in addition to causing the roller 462 to roll. The front lever 46 then moves the radiator 20 from... Figure 6 The shown open state is moved to Figure 7 The screen indicates the off state. Figure 6 In this state, the bottom 206 of the heat sink 20 is inclined relative to the upper wall 16 of the housing 10, for example, by one degree. Figure 7 In the current state, the bottom 206 is horizontal and enters the housing 10 through the upper opening 14. It is conceivable that the link 40 can be properly supported by the housing 10 without the frame 50; for example, the housing 10 may have features or similar structures for supporting the pivot 464.

[0039] The frame 50 is attached to the housing 10 to guide the movement of the connecting rod 40. Figure 8 and Figure 9As shown, the frame 50 may include a pair of frame portions 52 corresponding to a pair of link portions of the link 40, and a connecting portion 54 located between the pair of frame portions 52. Each frame portion 52 has an inner wall 522, an upper wall 524, and an outer wall 526. The inner wall 522 and / or the connecting portion 54 may be supported on the upper wall 16 of the housing 10. The outer wall 526 may be fastened to the side wall of the housing 10, for example, by engaging with a protrusion and a hole. A groove 56 is formed on the frame 50. The groove 56 extends through the inner wall 522 and the outer wall 526. A hole 58 is provided on the frame 50, and the hole 58 may also extend through the inner wall 522 and the outer wall 526. The groove 56 receives a pair of guide rails 424 to induce translational movement of the actuating link 42. The hole 58 receives the pivot 464 or a pair of pivot portions to realize pivotal movement of the front lever 46.

[0040] The clip 60 is used to secure the rear portion 204 of the heat sink 20 to the rear portion of the housing 10. It is conceivable that the housing 10 may have suitable features or similar structures to movably hold the rear portion 204 of the heat sink 20 at the rear of the housing 10. Notably, the clip 60 holds the rear portion 204 of the heat sink 20 at the rear of the housing 10, thereby allowing controlled tilting movement of the front portion 202 of the heat sink 20 relative to the housing 10 via the connecting rod 40.

[0041] refer to Figure 17-26 Another embodiment of the device 100 is designed, the device 100 having a connecting rod 70 and a corresponding heat sink 80 and frame 90, the other components shown can be combined with Figures 1 to 16 The components shown are essentially the same, therefore descriptions of identical components are omitted. Specifically, the connecting rod 70 may be in the form of a pair of connecting rod portions disposed on two opposite sides of the radiator 80. Each connecting rod portion may include an actuating connecting rod 72 and a front slider 74 pivotally connected to the actuating connecting rod 72. The front slider 74 is provided with a hole 742. The radiator 80 is provided with a pair of pins 82, each pin 82 being received in a corresponding hole 742. The hole 742 is designed, for example, to be elongated and inclined, such that the horizontal movement of the front slider 74 is converted into the vertical movement of the radiator 80 via the pins 82. For example, in Figure 19 In the open state, the pin 82 is located to the upper right of the hole 742, while Figure 20 In the closed state, the pin 82 is located to the lower left of the hole 742. In this embodiment, the connecting rod 70 does not need to be coupled to the corresponding spring 30.

[0042] The frame 90 may have an elongated hole 98 extending through its inner wall 922 and outer wall 926. The elongated hole 98 is adapted to the up-and-down movement of the radiator 80 by means of a pin 82.
